CT Salinity Data Logger

Data Storage Tags

DST CT logger is the smallest salinity and temperature monitor on world market. The Conductivity and Temperature Logger is especially designed as a archival tag for analysing fish migration, distribution, feeding behavior, vertical and horizontal movements. DST CT is ideal for research on marine animals as well. It weighs only 12g in water and 19g in air, the size is 15 mm x 46mm. The DST CT memory can store up to 65,374 measurements per sensor. Depth measurements can be skipped, increasing the memory size to measurements per sensor.

The small conductivity loggers are also used as CTD monitor or as a conductivity and temperure monitor whereas they are also ideal as stand-alone monitors for sampling in the ocean. They can for example be fastened to fishing gear, collecting valuable data. A protective housing for the DST CT is available.
